To all whom it may concern: 7 v

,Be it lmown that I, HERMA N GALL, a subject of the EmperorofAustria-Hungary, residing at Berlin, Germany, have invented certainnew and useful Improvements in Feeding and Moistening Devices forSecuring a Reinforcing-Strip Above the Perforated Edge of a Strip, ofwhich the following is a full, clear, and exact specification.

The invention relates to improvements 111' devices for perforating paperparticularly to improvements in the feedingand mois tening devices forsecuring a reinforcing strip above the perforated edge of the paper andin which a portion of a gummed reinforcing strip is advanced, moistened,cut off and attached along the perforations.

The novel feature of, and important improvement in the paper perforatoraccording to my present invention, as compared with the knowndevices,-is to be seen in the fact that the movementof the strip iscaused by a sliding piece which is positively operated by means of alever, and which carries a point engaging the paper, and coming free atthe end of each forward movement, re leases the paper.

The moistening of the strip is efiected in the well known manner bymeans of a closed, oscillating water receptacle containing a suitableabsorbing means and provided with springs, which when pressed againstthe gummed paper strip are compressed and which by their expansionduring thelowering of the water receptacle give the .paper strip freeand have the tendencyto cling to the absorbing means. By thisarrangement, a reliable feed for the strip is provided and the apparatusis protected against being soiled during the process of the moistening.

In the accompanying drawings: Figure 1 shows the general arrangement ofa paper perforator according to the present invention in its position ofrest, partly in elevation and partly in vertical section. Fig. 2 is atop plan view partly in horizontal section on line 21-13, Fig. 1. Fig. 3shows the device for giving to the paper its initial motion withthevmoistening device resting against the strip, and Fig. 1 shows it; atthe end of its course with themoistening device at rest. Figs. 5 and 6showthe pin engaging the paperstrip in two different positions.

Figs. 7 and 8 show a modified formof moistening arrangement in vertical;section Specification of Letters fatent. I 'Pathted-July 27., 1915throfug'hthe water receptacle, in Fig. 7 with the moistening devicepressed against the 1 paper strip and Fig.18with the moistening deviceswung downward.

The novel device forming thevobject of the present invention is suitablyused in connection with a paper, perforator comprising'the customaryvperforating punches which stand under the control of springs 71. andwhich are mountedso as to be vertically movable in tened reinforcingstrips 1, l have been brought fully into punching position, and

the frame 9, and are operated after the mois- I after the cutting devicewhich is verticallymounted in'the main frame a has been actuated- Theoperationof these parts is efiected in the ordinary well known manner bymeansof a lever mechanism 6, c, the tube 0 telescoping with a rod 6Zmounted vertically in the frame work a and in the base plate a andpassing through the arms j, z. The arrangement for advancing thereinforcing strips 1, 1 which are passed through channels provided withslots 30 at boths'ides of'the lower frame 4,0? of the machine consist ofa plate 5. sliding horizontally and guided by pins 26 working in slots25 in'said plate, Fig. 2. The plate 5 is connected by means oftensionsprings 6 to a-cross bar 7 and is provided with a'slotted portionsurrounding the guide rod on which the telescoping tube 0 works,toenable theplate 5 to slide freely. The sliding plate is, made of twoparts, one on each side of the guide rod, which parts are provided withsimilarlyfdirected' inclined faces 11. Upon the downward movement ofanarm 14 carried bythe movable tube 0 rollers 12 rotatable in suit ablebearings on said arms are pressed'upon the inclined surface 11,- andwhen the opera-f;

lever a movable abont b, a vertical down ward movement only can beimparted-to the rollers 12, they push the parts llan'd' the slidingplate 5 forward. The sliding plate 5 carries in addition pin shapeddevices 9 each side, see Figs. 5 and 6, thesepins are provided withpoints 9 engaging the paper strip 1. Each pin 9 is located in a verticalcasing 8 and is provided with a head 17, and each of them iscontrolledby a'spring 1Q. tending to force itdow'nward and is adapt :9tion is effected by pressing down thehandle ed to be operated by meansofaplat'e 16', on

the frame of the device. p The guideplates16..areupwardlyiinclined inthe direction of the forward motion and each of them is provided with alongitudinal slot 16 through which the shaft 9 of the pin passes andwhich engages said shaft just below the head 17 of the pin. By thisarrangement upon the movement of the sliding plate 5 toward the front,the pin 9 is raised from the position shown in Fig. 5 into the positionFig. 6, against the action of the spring 10, whereupon a bent levercontrolled by a spring 28, Fig. 2, and provided with a locking pawl 27,extends through the slotted opening 31 of the casing S and catches underthe stepped portion be tween the pin shaft 9 and the pin point 9 keepingthe pin in the position shown in Fig. 6 until upon the return movementof the sliding plate 5, under the pull of the spring 6, after the lever0 has been released, one arm of the bent lever 27 comes into engagementwith a projection 29, Fig. 2, on the side of the casing 61 thusreleasing the pin 9, so that it again engages the paper strips 1 1 21,21 are lever arms pivotally connected at 22 and located below the guidesand sliding plate 5, on both sides of the frame work a. The arms 21carry at their forward ends a transversely arranged water container 23,which at each end below the channels 30 for the strips has openings forthe reception of absorbent wicks 2% for moistening the paper strips 1, 1The lever arm 21, as will be seen in Fig. 1, is provided at its free endwith a plate 20 adapted to move beneath the roller 20 which roller iscarried by an arm 18 pivoted to the arm 14 so as to move in a vertical,plane and is kept in the position shown in Fig. 1 by the action of aspring 19.

The arm 1 1 by means of a clamping device 13 is clamped to the tubeoperated by the lever c.

The paper strips are fed from both sides from drums 2 located in themain frame and their tension is regulated by means of springs 3 pressingupon each of them.

From the slotted opening of each drum 2, each strip is passed over thebent-up end of the fixed guide, into the channel 30 in the frame-work tothe place where the perforating and cutting operations are performed.

The operation of the foregoing described device is as follows: Upon thedepression of the handle 0, the cutting means, the op eration of whichneed not be considered here, and the moistening device are operatedalmost simultaneously, the arm 18 kept in the vertical position by meansof the spring 19 presses upon the end of the arm 21, thus raising saidarm and pressing the wicks or sponges 24 in the water containermomentarily against the paper strip 1. During its depression the arm 18moves against the pressure of the spring 19 from the position shown inFig. 3 into that shown in Fig. 4, so that the levers 21, 21 are releasedand the 0011- tainer 23, 2 1 under the action of gravity returns intoits original position. lVhen the lever arm 0 is still further depressed,

the movement of the tube 0 caused thereby,

and the motion of the arm 14:, carries the rollers 12 mounted on thelatter down onto the sloping surfaces 11 in connection with the slidingplate 5, pushing the plate 5 for ward until the rollers 12 come to theend of the sloping surface 11. The paper strips are drawn forward withthe sliding plate 5 by the points 9 of the pins 9 engaging in the paper,until the engagement of the pins with the strips ceases, when the headsof the pins 9 enter the slots 16 of the sloping guides 16, disengagingthe points and locking the pins by means of the locking device, in themanner already described. When the lever c is released and the rollers12 return along the inclined surfaces 11, the sliding plate 5 is carriedback into its initial position by the pull exerted by the spring 6 andthe pins 9 9 released from the locking device 27 by the contact of thearm thereon with the projection 29. After being released, the pins 9 9under the influence of the springs 10 are pressed down" ward and engageagain with the paper strips 1, ready to push them forward.

As shown in Figs. 7 and 8 the moistening device carried by the levermechanism 21, 22, 21 comprises a water container eX- tendingtransversely and having at each of its ends a perforated device insertedinto or formed with the container which holds the absorbing material formoistening the gummed strips. Each of the parts 23 is provided with asmall central tube, which is separated from the absorbent material inwhich is located a spring 23 normally projecting beyond the absorbentbody 24, the spring being prevented from coming into actual contact withthe absorbent body 261 by the surrounding tube. If the water container23 is pressed against the gummed strengthening strip 1 through theaction of the lever mechanism, on depressing the handle, the spring 23is compressed, see Fig. 1. The strength of the spring is so calculatedthat a perforation of the paper strips or a displacement of the same outof the proper course is avoided. When the water container descends intoits original position, after the release the lever mechanism 21, 21 andafter the absorbent body 24 has momentarily been pressed into contactwith the strip, the spring 23 is released and its upper coil pressesagainst the gummed strip, so that the latter is set free and can bemoved forward without impediment, even when the absorbent materialthrough wear and tear has become sticky.
